A check valve (26) prevents an air flow from the pre-filter section into the post-filter section by bypassing the filter unit, and which allows an air flow from the post-filter section into the pre-filter section by bypassing the filter unit with proportionate pressure ratios so that a transporting of foreign particles (28) from the post-filter section into the pre-filter section is made possible.",
